seminal vesicles

Highly atypical cells are a normal finding in the seminal vesicles of about 80% of older men. The nuclei are large, irregular, hyperchromatic, and show prominent nucleoli. The atypia is degenerative and not observed in the seminal vesicles of young men.

Differential diagnosis

When encountered in needle biopsies, it may be mistaken for adenocarcinoma.
